Joe Russo and Anthony Russo aren’t forgetting their roots, as the directors who brought you Captain America: The Winter Soldier are returning to Community again for the Season 6 premiere.

The brothers were the primary directors on Community when it began, starting with the pilot episode they helmed, and in its five seasons so far, between the two of them, they have directed 33 episodes.

Those last two episodes, impressively, come from Season 5 – especially notable since the Russo brothers were in the midst of editing their acclaimed hit, The Winter Soldier, at the time, but still took time to return to Greendale.

Shirley, Community fans are going to be disappointed with this news. But alas, it’s true: Yvette Nicole Brown is departing the fan favorite comedy after five seasons.

Brown — who has played Shirley Bennett since the 2009 launch of Community — confirms to TV Guide Magazine that she has asked to be released from her contract for personal reasons. Sony Pictures TV and executive producers Dan Harmon and Chris McKenna have honored her request.

The actress says the change was necessary in order to take care of her ailing father. “My dad needs daily care and he needs me,” Brown says. “The idea of being away 16 hours a day for five months, I couldn’t do it. It was a difficult decision for me to make, but I had to choose my dad.”

That means Brown won’t be a part of the group that makes the transition from NBC to Yahoo! Screen for Season 6. “Yvette was an integral part of Community and is irreplaceable. We are sad to see her go and wish her the very best,” Harmon and McKenna said in a joint statement.

They should have introduced a new character or two last season. Though it was a passable season it was in desperate need of some new dynamics. Perhaps it wouldn’t have run out of steam in the final quarter. For some reason Shirley not being there is more daunting than Glover’s departure. However, Britta is the only character who if absent this would be a no go for me.

they introduce the jonathan banks’ character and it was interesting that he eventually kinda got paired up with abed. i hope there is somebody new added to the group. and i hope they manage to get some interesting guest stars again this season. having mitch hurwitz and vince gilligan was kinda cool last season.

Casting continues on the sixth season of perpetually uncanceled college sitcom Community. Last week, Keith David and Paget Brewster joined the cast. Now, EW can exclusively reveal that Community is set to finally introduce Britta’s parents: Martin Mull and Lesley Ann Warren will play George and Deb Perry in the second episode of the season.

Mull was most recently seen on the small screen as one of the titular Dads, while Warren’s most visible role in recent years was on In Plain Sight. More importantly, both Mull and Warren were in Clue. (Colonel Mustard and Miss Scarlet, respectively.) This could imply that s06e02 will be some sort of elaborate nesting-doll meta-murder mystery, where Britta and her parents play a board game loosely based on Clue—let’s call it Inkling—and while they try to solve the murder in the board game, they have to also solve a murder in real life, but it turns out that the murder was just a metaphor for emotional neglect.

That’s probably not what the episode is about, but this being Community, there’s already a subreddit building Inkling on a 3D printer. Community‘s sixth season will debut on Yahoo Screen in winter 2015.
